I had to stop the car by the side of the road to capture this whirly-whirly. It was a couple of kilometres away and the dust reached high into the sky. It was probably fueled by a farmers recently plowed paddock.
Below is a version of the photograph that I had a quick play around with in Photoshop Elements so that the dust was more visible (perhaps at the expense of realistic colours!)
Taken with a Canon PowerShot SX30 IS.
